An emergency QB is nice, but if you get to that point in a single game, the game is pretty much over anyway. You can just pick whoever to play QB or just run the wildcat for the rest of the game. And, if you happen to lose both QB's in a single game, you can have your pick of veteran backup guys at practice by the next day.

Bottom line is that if you lose both guys to something that keeps them both out for more than the current game.......it doesn't really matter who you get at that point. You are done.

He probably knows hw to use his size and strength better than LaFell tbh

Or maybe they just want someone who isn't familiar with the playbook, has done nothing in the NFL and who doesn't try to run his routes if he knows the ball isn't coming his way. How much time was wasted discussing and signing this 5th WR?

From NFL.com::

STRENGTHS McNutt is reliable to get his hands on the ball and make a tough catch when it's thrown anywhere near him. He has good awareness to get open on broken plays and drag his feet along the sidelines. He is a viable possession-type option for quarterbacks looking to pick up a quick first down.

WEAKNESSES

McNutt can struggle when running routes across the middle. There are consistency and effort issues when blocking and running decoy routes that aren't intended to him, and he can struggle off the line if he isn't decisive and powerful with his first step
